[rules-users] 6.1.0.beta4 and identified a rule pattern inducing memory leaks

Ciao, I'm using 6.1.0.beta4 and I identified in my application a rule pattern inducing memory leaks. I try to attach rule, screenshots, and javacode to replicate the issue. IF the rule "After No data received within the last 1 hour Error, now resumed" is included, memory leaks happens, and pretty quickly. IF such rule is commented out, application do manage to keep alive. [>] Question kindly is: is this normal on 6.1.0.beta4, or shall I go ahead and raise a JIRA for this, please? This time I ask in the mailinglist first, just because last time I experienced a similar issue and raised JIRA, but in fact at the end was just another way to replicate a known issue.
